Elastic-plate fixing structure of tray for data accessing device

Abstract

An elastic-plate fixing structure of a tray for receiving a data accessing device includes a base case and a fastening unit. The base case includes a coupling portion. The fastening unit includes an elastic buckle piece, a pressing elastic plate, a vibration absorbing pad, a first clamping plate, a positioning protrusion and a second clamping plate and has a clamping space between the first clamping plate and the second clamping plate for receiving the vibration absorbing pad. The elastic buckle piece is coupled to the coupling portion. The pressing elastic plate is connected to the elastic buckle piece. The vibration absorbing pad is positioned between the elastic buckle piece and the pressing elastic plate. The first clamping plate is connected to the elastic buckle piece. The positioning protrusion is formed on the first clamping plate. The second clamping plate is curvedly connected to the pressing elastic plate.

Description

RELATED APPLICATIONS[0001]This application claims priority to Taiwan Application Serial Number 106214154, filed Sep. 22, 2017, which is herein incorporated by reference.BACKGROUNDField of Disclosure[0002]The present disclosure relates to an elastic-plate fixing structure of a tray. More particularly, the present disclosure relates to an elastic-plate fixing structure of a tray used for receiving a data accessing device, in which the elastic-plate fixing structure includes a base case and a fastening unit, and a sidewall of the base case is coupled with the fastening unit, and a vibration absorbing pad is positioned between an elastic buckle piece and a pressing elastic plate, so as to provide a traveling space for a positioning protrusion of the elastic buckle piece to be engaged with or disengaged from an engaging hole of the data accessing device, thus achieving the object of rapidly inserting or withdrawn the data accessing device in or from the tray.Description of Related Art[00...

AI Technical Summary

Benefits of technology

[0012]According to another objective of the disclosure, the pressing elastic plate of the fastening unit is directly connected to the outer casing of the chassis, and thus not only the vibration absorbing pad can be used to reduce the vibration of the chassis transmitted to the data accessing device, but also the vibration absorbing pad absorbs the vibration energy generated when the data accessing device operates, thereby maintaining the data accessing device in an stable balance to eliminate vibration or resonance between the data accessing device and the chassis, thus improving the performance of the Rotational Vibration Index (RVI) test, and preventing the data accessing device from being damaged by vibration and tolerance during operation and testing. Therefore, the service life of the data accessing device in prolonged.

Problems solved by technology

However, when the aforementioned data accessing device is operated, high-frequency vibration, or external vibration transmitted to the data accessing device from the server chassis by external force is usually generated.

If the data accessing device is simply mounted on the fixed frame or the tray by means of screw locking, the data accessing device will often be caused continuous high-frequency vibration or resonance due to the lack of appropriate anti-vibration design.

Therefore, not only screws may be easily loosed from the data accessing device, but also the data accessing device is damaged to reduce service life of the data accessing device.

Although a tool-less fixing frame or tray design may quickly assemble to or disassemble from the data accessing device, however, if the fixed convex hull structure fastens the data accessing device too tight, problems that the data accessing device is difficult to be assembled to or disassembled may be happened; if the fixed convex hull structure fastens the data accessing device too loose, problems that reliability issues and performance test results of rotational vibration index are poor may be happened.

Therefore, the service life of the data accessing device in prolonged.
